Traces of sunscreen agents in the snow at the North Pole – “Many of the contaminants we have analysed had never been identified in Arctic snow before”

20 December 2023 (Ca’ Foscari University of Venice) – Traces of sunscreen agents were found at the North Pole, on the glaciers of the Svalbard archipelago. They were mainly deposited in winter, when night falls over the Arctic. A study conducted by researchers from Ca’ Foscari University of Venice and the Institute of Polar Sciences – National […]

Mountain villages fight for future as melting glaciers threaten floods – “Until 1978, this whole place was a glacier. The pool of water came later.”

By Charlotte Greenfield 22 November 2023 (Reuters) – On the steep slope of a glacier jutting through the Hunza valley in Pakistan’s mountainous far north, Tariq Jamil measures the ice’s movement and snaps photos. Later, he creates a report that includes data from sensors and another camera installed near the Shisper glacier to update his […]

Swiss glacier watcher warns 2023 heat wave threatens severe melt again after record 2022 – “We can definitely say that we had very high melting in Switzerland and in Europe in general”

By Jamey Keaten 1 September 2023 GENEVA (AP) – A top glacier watcher has warned that a warm early summer combined with a heat wave last week may have caused severe glacier melt in Switzerland, threatening to make 2023 its second-worst year for ice loss after a record thaw last year. Matthias Huss of the GLAMOS […]

We reached the glacier just as it collapsed – The world’s widest glacier is melting and changing predictions about our planet’s future – “It looks nearly as dramatic as the Larsen B collapse”

By Elizabeth Rush 13 August 2023 (The Atlantic) – Out on the bow of the R/V Nathaniel B. Palmer, the air is dense and almost warm. We have punched through miles of Antarctic ice floes to reach the Amundsen Sea’s foggy interior. I want to honor the remaining distance between us and Thwaites Glacier’s calving […]

Heat dome shatters all-time U.S. records as Europe roasts – “Brutal” heat wave brings triple-digit temperatures from Chicago to New Orleans – 110 million people exposed to dangerous heat

By Andrew Freedman 24 August 2023 (Axios) – In a summer featuring countless heat domes and record-high temperatures and heat indices, the season appears to have saved the worst for last. The big picture: A sweltering, stagnant air mass is draped across the Central U.S., resulting in “dangerous,” “searing” and “brutal” heat. Meanwhile, southern Europe is also seeing another bout of […]

The location of climate tipping elements in the cryosphere (blue), biosphere (green) and ocean/atmosphere (orange), and global warming levels their tipping points will likely be triggered at 1.5°C. Researchers see signs of destabilisation already in parts of the West Antarctic and Greenland ice sheets, in permafrost regions, the Amazon rainforest, and potentially the Atlantic overturning circulation as well.

Climate collapse could happen fast – “For a long time, we were within the range of normal. And now we’re really not. And it has happened fast enough that people have a memory of it happening.”

By Lois Parshley 20 July 2023 (The Atlantic) – Ever since some of the earliest projections of climate change were made back in the 1970s, they have been remarkably accurate at predicting the rate at which global temperatures would rise. For decades, climate change has proceeded at roughly the expected pace, says David Armstrong McKay, a […]

Shrinking Arctic glaciers are unearthing a new source of methane – “The amount of methane leaking from the springs we measured will likely be dwarfed by the total volume of trapped gas lying below these glaciers, waiting to escape”

By Catherine Martin-Jones 6 July 2023 (University of Cambridge) – As the Arctic warms, shrinking glaciers are exposing bubbling groundwater springs which could provide an underestimated source of the potent greenhouse gas methane, finds new research published today in Nature Geoscience. The study, led by researchers from the University of Cambridge and the University Centre in Svalbard, […]

Humans have pumped so much groundwater that we’ve nudged the earth’s spin – “As a resident of Earth and a father, I’m concerned and surprised to see that pumping groundwater is another source of sea-level rise”

WASHINGTON, 15 June 2023 (AGO) – By pumping water out of the ground and moving it elsewhere, humans have shifted such a large mass of water that the Earth tilted nearly 80 centimeters (31.5 inches) east between 1993 and 2010 alone, according to a new study published in Geophysical Research Letters, AGU’s journal for short-format, high-impact research with […]

Accelerated melting of glaciers in Greenland – Greenland’s glaciers have lost at least 587 cubic km of ice over the last century

26 May 2023 (University of Leeds) – A study has found widespread mass loss of glaciers and ice caps in Greenland since the start of the 20th century. The research provides critical insights into long-term changes to the glaciers and ice caps as a result of climate change, which has contributed about one fifth to […]

WMO annual report highlights continuous advance of climate change – “While greenhouse gas emissions continue to rise and the climate continues to change, populations worldwide continue to be gravely impacted by extreme weather and climate events”

Geneva, 21 April 2023 (WMO) – From mountain peaks to ocean depths, climate change continued its advance in 2022, according to the annual report from the World Meteorological Organization (WMO). Droughts, floods, and heatwaves affected communities on every continent and cost many billions of dollars. Antarctic sea ice fell to its lowest extent on record […]
